What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its wavelength, frequency, and amplitude.

What does the term 'wavelength' refer to?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

What is 'frequency' in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Define 'amplitude' in wave motion.

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

What type of wave is a sound wave?

Back

A sound wave is a longitudinal wave that travels through a medium (solid, liquid, or gas) by compressing and rarefying the particles.

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium; they include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s) or about 186,282 miles per second.

How do radio waves compare to visible light in terms of wavelength?

Back

Radio waves have longer wavelengths than visible light, making them capable of traveling longer distances.

What is the principle of superposition in wave motion?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.
